Castlevania Circle of the Moon

Enter CROSSBOW as a name and start a new game. If you entered the code correctly, the word Shooter will appear on the option screen. Nathan will have a substantial number of hearts, extra sub-weapon damage, and can use the Homing Dagger sub-weapon in this mode.

In the Battle Arena, equip a good DSS Summon Combo (for example, Uranus + Cockatrice). Press Start, select "Items", then "Use", and use a "Mind High" (not a "Mind Restore" -- however they can work, but you will need to be extremely fast). Immediately after exiting the pause menu, press the DSS button. When your character is done casting, press Down, Forward, Up, Attack. If done fast enough, you should have pulled off a summon in the Battle Arena.

Enter GRADIUS as a name and start a new game. If you entered the code correctly, the word Fighter will appear on the option screen. Nathan will be stronger and able to sustain more damage. There are no trading cards in this mode.
